PAVING TILE OR BRICK.V

SPECIFICATIQN forming port of Letters Patent No. 400,477, dated April 2, 1889. Application filed October 2.2, 1888 Serial No.288f786. (No specimens.)

To all whom it may' concern:

Be it known that I, CHARLES M. OCONNER, of the city of Lock Haven, county of Clinton, and State of Pennsylvania, have invented certain new and useful Improvements in Brick or Paving Tile, of which the following I am aware that the edge of one tile hasV heretofore been secured to that of another by means of rigid projections from one fitting into corresponding indentations in the other. The objections to this method are that the projections are rigid and unyieldingg hence after laying one tile, for example, having a projection, when another tile is to be laid opposite it having a corresponding depression itis necessary to have room enough to permit the tile last laid to pass down outside of the projection until theY depression comes opposite to it. The resultis that when a finishingcourse of tile is to be laid next a curb, for example, and it is desirable to have a tight iit all around the tile, it is impracticable to secure it, because there is not room enough to slip the tile in place past the rigid proj ection.A I overcome this difficulty in large measure by having corresponding sockets in all of my bricks or tiles, and by providing a loose ball to approximately ill the sockets when the tiles are laidin place. a course of tile then in laying the nextcourse to place a' loose ball in one of the sockets of either course and press the tile to place Within less space or working-room than would be required if a rigid projection from one of the tiles were employed, because the ball will revolve in its'socket and aid the pressure of the tile last laid vertically into position; or two tiles Athat are to lie adjacent to each other and be bound together by the ball may be simultaneously laid by inclining them toward each other and placing the ball in one of the sockets between the tiles, and then pressing I ain able, therefore, to first lay u both the tiles down to position. I find in practice that the difficulty of getting tiles into place so as to fill a given space is consider`= ably diminished by using loose balls instead of rigid projections. I also ind that a given space to be filled by tiles or bricks can be filled more completely and with less joint-spaces where loose balls are used to bind the tiles to= gether than where rigid projections are used.

In the accompanying drawings, Figure l is a perspective view of a Vsection of pavement constructed with my device, having the edges exposed so as to show the sockets ,and Fig. 2 is a plan view, partially in section, of aportion of pavement showing the relation and position of the balls and sockets.

In tho following description I wm dosig-i' nate the subjects of the drawings as tiles,

though it should be understood that bricks or any form of paving or building materials are intended to -be comprehended.

Referring to the letters on the drawings, A represents a section of pavement, being com posed of square and triangular blocks, the triangular blocks being required to iill in spaces in construct-ing a rectangular form of pavement. B" represents one of the blocks. C represents semi-spherical sockets in the sides of the blocks. D indicates spheres or balls made to it within the sockets. Vhen in position, the balls D are half buried in the sockets and half protruding beyond the surface of the edges of the tile. The sockets are placed in corresponding positions in the dierent tiles, so that when the tiles are placed in position in paving, the socket in one tile shall open into a socket in another. A ball being rst placed in position and the tiles laid, the sockets in two adjoining tiles inclose it, so that the edges of the tiles shall come in contact and be secured vertically in position. 'If

the loose ball-connection is used, we have the 4 ets within its edges and loose balls or spheres fitting Within the sockets, as and for the purpose set forth.

In testimony of all which I have hereunto subscribed my name.

CHAS. M. OCONNER.
